operated arm carrying a contact finger connected Referring to the drawing, a drive shaft l0 is 55 equipped with a female clutch member Ii loosely mounted thereon and engaging a male clutch member I2 fastened on the main shaft I3 of the cigarette machine, wrappim machine, or other type of machine to which the tipper is attached. To the shaft I3 is attached a helical gear I4 meshing with a helical gear I5 mounted on the jack-shaft I6, the shaft It also -carrying a sprocket (not shown) which drives a chain I1 over a sprocket (not shown) mounted on the drum-shaft I8.

Shaft I8 carries a pinion Il meshing with a gear mounted on shaft 2i, the gear 20 meshing with a gear 22 which drives a gear 23. Gears 22 and 23 are mounted on shafts 24 and 2Q respec-` tively, and shafts 24 and 25 carry the feed rollers 26 and 21, respectively, which coact to feed the web of tipping material C.

The shaft I8 also carries a gear 28 meshing with an intermediate gear 29 on shaft 30, gear 29 meshing with a gear 3i mounted on shaft 32. 0n shaft 32 is also mounted a gear sin. which drives a gear 33 mounted on shaft i4. and the gear33 drives a gear 35 mounted on shaft Si. A pinion 31 on a shaft 33, which also carries a pinion Sla, is driven by the gear 3E; and the pim ion 31a drives a gear @t mounted on a shaft it supported in bearings cf the paste pot 4i.

The paste pot 4i is provided with a scrar or doctor 42 which is slidably mounted on the paste pot and equipped with an adjusting screw t; for adjustment of the scraper 42 closer or farther away from the paste wheel G4 and thereby controlling the amount of paste on the latter. As the wheel 44 rotates it transfers the paste adhering to its periphery to a distributing roller 45 which in turn delivers the paste to a rotating seg.- mental paste applicator 46 clamped on shaft 36.

The web of cork or other tipping material unwbund from a reel R by the feed rollers 2e and 21, which advance the tipping material at a speed substantially less than that of the cigarette paper.l P, passes through a stationary guide 41, and its leading end enters the clearance space between the concave 4l and the revolving metallic drum 49. This clearance is slightly greater than the thickness of the tipping material. After a length of the web C sumcient for two cork tips has entered said space, the web is nipped against the concave by the cutting edge of eitlier of the proper length of tip material at the entrance tol this space and sever it across a ledger. plate integrally formed with the concave 4|,nd slightly raised thereon adjacent said entrance. 'Ihe cut strips are then pushed along in said space by the cutting edges ofthe cutters which travel at a linear speed equal to that of the cigarette paper, until their leading .ends are nipped'between the respective protuberance and the raised segment of a roller, as will be presently described.

' While the ledger plate hasv been described as integrally form'edjwith the concave.. it should be 'l understood that hardened steel inserts maybe used instead;

The web of wrapping material P is from a reel (not shown) over a metallic roller 5I and around a stud 52 carried by the frame 53. 0n the stud 52 is pivotally mounted a spring-tensioned arm 53a which during normal operation is held in vertical position by a 4latch 54. The arm 53a carries studs 55 and 56, and the wrapper web P passes over said studs and between the drum-49 and a roller 51 as it is drawn upwardly by continuously rotating rubber feed rollers (see Fig. 2) driven from the shaft I8 by a gear train (not shown).

The revolving paste applicator 4B, which rotates at a greater linear velocity than the speed of the traveling wrapper web P rubs over the section of the latter spanning the studs 55 and 56 and thereby applies paste to the continuously moving wrapper web at the proper intervals. The pasted wrapper web P is then carried around the roller 51; and the cut portion of tipping material which is being advanced by the cutting edge of either cutter 50 or 50a into register with the web P, is pressed thereon as it is nipped between the respective protuberance of the drum 43 and the raised segment of roller 51.

A cam ti; mounted on shaft I8 is provided with diametrically opposite steps 59 which each successively engage the spring-pressed arm Eil and permit the same and a metallic contact finger 5I fastened to its hub to momentarily move inward.

In case the reel of tipping material is exhausted or broken, the contact finger 6l during its repeated inward movementeventually makes unobstructed contact through a 'slot in the concave 48 with a narrow groove in either protuberance of the drum 49, thus completing a circuit through and energizing a solenoid 63" which thereupon pulls down thev latch 54 pivotally mounted on a stud it and thereby frees the arm 53a. Whenever lthe arm 53a is thus freed it swings away from thepath of the revolving paste carrier 46 with the wrapper web and in so doing, prevents the further application of paste to the wrapper web. At the same time. the electromagnet Si, which is connected in parallel with the solenoid 63, is also energized and attracts an `arm II connected to the female clutch member I I, thus moving the arm 68 as indicated by the dotted arrow to disengage the clutch members II-I2 and stop the cigarette machine, or other type of machine to which the tipper is attached.

For this purpose, one of the lines 81. which are supplied with current from a suitable source of electric current, not shown, is connected by a lead Il to astationary contact 80. When the arm 6I engages one of thc steps 50 of the cam Il and the inner end of the contact maker II enters either of the grooves in the protuberances of the drum 4I, the outer end of the contact maker is pressed against the contact so that the current flows through a wire 1l to the solenoid u. The latter is thus energized and trips the latch I4 heretoforedescribed; 4and the` current flowingl through the wire 1I to` the lectromagnet il energizes it, thereby `actuating the arm 66 to disengage the clutch members I'i and I2, and returns to the other line through the lead 12.

, In case the wrapper web P is exhausted or broken, the eiectromagnet 65y is energized through a branch circuit comprising la lead 13 connected to the line 61 and the roller 5I and a contact finger 14 which is then free to make contact with the peripheryof the roller Il'. The current then passes through the fingen-*14 and flows to the eiectromagnet through a wire `15, returning to the other line 81 through the lead 12.
